sclone:  spectral cloner
sclone   [flags] < floatsams > floatsams
        N:      fft length [1024]
        R:      sampling rate [44100]
        M:      window size in samples [4096]
        D:      decimation factor in samples [1024]
        I:      interpolation factor in samples [1024]
        a:      clone attenuation factor [1.]
        o:      bin offset  [0]
        n:      number of bins to clone [31]
        S:      bin skip [0]
        P:      pitch factor [0.]
        t:      threshold generator [.005]
        q:      maintain phase coherence
        s:      synthesize analysis input

a: attenuation factor for each copy
S: number of bins to skip, making model
n: number of bins in model
o: bin offset to start assembling model

Basic result is to inelegantly screw up
the high end of signal
I never got great results with this,
but I haven't spent a lot of time
with it either.
